Sesame Soy Eggplant Tomato Penne

Salting the eggplant and allowing it to rest for at least fifteen minutes draws out both water and any residual bitterness, so the flesh cooks down softer and more concentrated when sauteed in olive oil. Once the eggplant has absorbed the oil fully, it behaves like a sponge for the surrounding sauce, pulling flavor into each dense, yielding piece. Soy sauce brings a fermented, savory quality that layers directly on top of tomato's own natural glutamates, creating a double-umami effect that gives the sauce a richness typically associated with meat-based preparations. Sesame oil is added off the heat at the very end to preserve its raw, toasted fragrance - cooking it destroys the volatile compounds that make it distinctive. Toasted sesame seeds scattered over the finished pasta provide a nutty crunch that contrasts the soft eggplant. Fresh basil introduces a herbal brightness at the finish, and the base of onion and garlic cooked at the start gives the sauce its aromatic foundation.
